How is the survey conducted?
Basically, all data of the Reiseanalyse are based on surveys of the German-speaking population in Germany. Within the scope of the Reiseanalyse, more than 12,000 interviews are conducted in Germany. Of these, 7,500 are face-to-face interviews lasting around one hour and 5,000 online. The survey focuses on holiday travel with at least one overnight stay. A distinction is made between holidays of five days or more and short breaks of two to four days. The findings in each case as well as the sample of the Reiseanalyse are representative for the German-speaking resident population in Germany in private households, aged 14 years and older (RA face-to-face) or aged 14 to 75 years (RA online).
RA face-to-face survey:
The RA face-to-face deals with the travel behaviour during long holiday trips (from 5 days duration) and with holiday-related attitudes, motives, activities and interests. With the RA face-to-face, the respondents are determined by a multi-stage random selection process: Ipsos, FUR’s long-standing partner for fieldwork and data collection, uses a close-knit sample network with over 1,400 survey points. These so-called sampling points are distributed throughout Germany according to the population distribution. In each sampling point Ipsos randomly draws a start address. According to the random-route principle, the interviewers visit the target households and determine the target person using a random key (birthday key). The interview will be conducted directly or at a later agreed time with this person in their household. An interview takes about 60 minutes on average. The results are representative of German-speaking persons aged 14 and over living in private households in Germany (2017: 69.6 million persons).
RA online survey:
The RA online focuses on the travel behaviour during short breaks (2 to 4 days duration) and the travel planning, the customer journey of the holiday-makers. A sample of over 150,000 respondents will be selected from an online access panel of Ipsos. Panel members are recruited through a variety of measures, so that the population strata are broadly covered. Very strict panel management rules also ensure that a panel member is not repeatedly interviewed on a given topic within a given period of time. So-called panel effects are thus greatly reduced. Taking these exclusions into account, a sample is drawn online which has the same distribution for the characteristics of gender, age and place of residence as the official statistics for the population aged 14 to 70 (2017: 58.8 million persons). The online surveys of the RA 2019 will extend this basis to the 14 to 75-year-old population.
Germans and German-speaking foreigners:
Since the RA 2011 German-speaking foreigners with permanent residence in Germany are also part of the universe. As a consequence, from RA 2011 the results are generally presented for the entire German-speaking resident population aged 14 and older (German citizens and German-speaking foreigners).
All partners of the Reiseanalyse receive a detailed method description with more information about the universe, the selection of the respondents, the survey method, sample, interviewer controls, structure weighting and projection of the Reiseanalyse in a separate method book. For RA online, the selection of respondents, the recruitment of panel participants and quality assurance are specifically and additionally described.
